Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Wait at least 10 minutes after disconnecting the battery.

2. Address Faulty Connections

Inspect airbag connectors and wiring harness:
- Remove the lower dash panel to access airbag connectors.
- Reconnect any loose or corroded connectors.
- Use dielectric grease on connectors to prevent corrosion.

3. Replace Faulty Components

If error codes indicate a specific component failure (e.g., airbag module, seatbelt pretensioner):
- Remove the affected component according to manufacturer specifications.
- Install the new component, ensuring all connections are secure.
- Torque bolts to factory specifications (refer to service manual for values).

4. Reset the Airbag System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag codes.
Perform a system check to ensure the airbag light turns off.
